.SH NAME
std::num_get::~num_get \- std::num_get::~num_get

.SH Synopsis
   Defined in header <locale>
   protected: ~num_get();

   Destructs a std::num_get facet. This destructor is protected and virtual (due to
   base class destructor being virtual). An object of type std::num_get, like most
   facets, can only be destroyed when the last std::locale object that implements this
   facet goes out of scope or if a user-defined class is derived from std::num_get and
   implements a public destructor.

.SH Example


// Run this code

 #include <iostream>
 #include <locale>

 struct Destructible_num_get : public std::num_get<wchar_t>
 {
     Destructible_num_get(std::size_t refs = 0) : num_get(refs) {}
     // note: the implicit destructor is public
 };

 int main()
 {
     Destructible_num_get dc;
     // std::num_get<wchar_t> c; // compile error: protected destructor
 }
